摘要：Now days, we have seen that many cardiac diseases are diagnosed by Electrocardiogram test. Therefore ECG analysis is widely studied and applied in clinic. The recorded ECG signal in clinical information is corrupted by various kinds of noises. To obtain true ECG signal from noisy observations can be formulated as problem of signal denoising. In this paper a new threshold function is proposed. There were different thresholding functions introduced by the authors. In this paper proposed method is compared with the existing methods. SNR is the powerful parameter to decide the quality of signal. By using this proposed method the SNR is obtained highest after comparing the results of different methods used for denoising the ECG signal. As well as RMSE is reduced to obtain the true ECG signal.
